Flat and low-slope roofs fail differently than pitched shingle roofs — ponding water, seam separation, and membrane punctures need specialized diagnosis.
A flat roof leak rarely shows up directly above where the water actually entered — membrane systems move water laterally before it drips through.
We also test repaired seams for a proper bond before leaving, rather than assuming a visual check is enough.
Every Flat Roof Repair technician carries current North Grafton, MA licensing for commercial roofing work.
We coordinate timing to reduce impact on tenants or foot traffic wherever possible.
Written Flat Roof Repair estimates cover membrane type, repair scope, and labor upfront.
Hot-air welding equipment ensures a proper bond on every TPO Flat Roof Repair repair.
